8.3.15 FGOUT Signal

The MCT8316Z device also has an open-drain FGOUT signal that can be used for closed-loop speed control of

a BLDC motor. This signal includes the information of all three Hall-elements inputs as shown in Section 8.3.15.

In the MCT8316ZR (SPI variant), FGOUT can be configured to be a different division factor of Hall signals as

shown in Section 8.3.15. In the MCT8316ZT (Hardware variant), the default mode is FGOUT_SEL = 00b.
